Title: Metal salts of sulphur-containing carboxylic acids and stabilisation of polyvinyl chloride therewith
IPC: C08K5/03
Filed: 1963-06-10
Abstract: The invention comprises compounds of the general formula <FORM:0978676/C1/1> wherein A and B each represent a straight chain or branched alkylene group containing up to 6 carbon atoms and which may carry a phenyl substituent group and Q is Zn, Ca, Cd, Ba or dialkyl tin. Specified alkylene groups are methylene, ethylene, propylene, methyl-ethylene, phenyl-ethylene, methyl-propylene and phenyl-propylene. The preferred compounds are those in which A and B are ethylene groups. The compounds are prepared from the thio-bis (alkylene-b -carboxyacrylates) and a suitable base containing the divalent metal grouping, e.g. dialkyltin oxides, CaO, ZnO, CdO or barium hydroxide. Suitable dialkyltin radicals are dimethyl-, dibutyl-, diethyl-, dipropyl-, dipentyl- and dioctyl-tin, the normal and lower alkyl derivatives being preferred. The compounds are used as stabilizers for polyvinyl chloride compositions (see Division C3). Examples describe the preparation of (1) the dibutyltin salt, (2) the Zn salt, (3) the Ca salt, (4) the Cd salt and (5) the Ba salt of thio-bis(ethylene-b -carboxyacrylate).  Thio-bis(ethylene -b - carboxyacrylate) is prepared from thiodiglycol and maleic anhydride.ALSO:Polyvinylchloride compositions are stabilized by the incorporation of at least 0 01% by weight a compound of the formula <FORM:0978676/C3/1> wherein Q represents Zn, Ca, Cd, Ba or dialkyl tin and A...B are each a straight chain or branched alkylene group containing up to 6 carbon atoms and optionally carrying a phenyl group. The compounds are particularly effective against thermal and light-induced degradation, especially when used in combination with other additives, e.g. polyhydric compounds, including sorbitol. The compounds can be used singly or in admixture and with other stabilizers, anti-oxidants, uv light absorbers, dyes, pigments, fillers, antistatic agents and plasticizers. Amounts varying between 0.01-10% by weight of unstabilized polymer composition may be used. Example 6 describes the preparation of compositions containing a polyvinyl chloride resin and 2% by weight of the Zn, Ca, Cd and Ba salts of thio-bis(ethylene b -carboxyacrylate), a mixture of the Zn and Ca salts and a mixture of the Cd and Ba salts.

Title: Improvements in and relating to control gear for steam turbines
Inventor: CALDWELL JOHN
IPC: F01K7/24
Filed: 1958-07-18
Abstract: 936,851. Engine stop-gear; steam turbine plant. ENGLISH ELECTRIC CO. Ltd. Oct. 6, 1959 [July 18, 1958], No. 23110/58. Classes 110 (3) and 122 (4). The high pressure stop valve 110 and throttle valve 109 of a steam turbine are controlled by a load-sensitive governor 4, Fig. 1, to close simultaneously in the event of loss of load. Where reheat is used the reheat emergency valve 111 and the reheat interceptor valve 112 are similarly controlled. The turbine shown drives a main alternator 1 and comprises high, intermediate and low pressure cylinders 101, 102 and 103 respectively and reheaters 105 between cylinders 101 and 102. The speedsensitive or primary governor 104 is connected in the normal manner to the valve actuators 9, 10, 11 and 12 of the valves 110, 109, 112 and 111 respectively. An auxiliary alternator 100 coupled to the main alternator is connected by lines 3 to the load-sensitive or secondary governor 4. The throttle valve and reheat interceptor valve spindles are mechanically connected respectively to on-off switches 15, 18 which control the circuits 5, 8 of the actuators 9, 12 respectively of the valves 110 and 111 so that these circuits are open when the valve controlling them is closed. A switch 16 sensitive to the exhaust pressure of cylinder 102 is connected by a circuit 17 to the secondary governor 4 to reset the latter when the exhaust pressure drops below a predetermined value and the control of valves 109-112 is then returned to the primary governor 104. On loss of turbine load the stop valves 110 and reheat emergency valves 111 are closed by the secondary governor 4 simultaneously with the throttle valves 109 and interceptor valves 112, and due to the switches 15, 18, re-open automatically when the valves 109 and 112 are closed. If, however, a throttle valve 109 or interceptor valve 112 is faulty and does not close, the associated stop valve 110 or emergency valve 111 will remain closed even after the secondary governor has been re-set by the switch 16 since the servomotors of those valves have insufficient power to re-open them against full boiler pressure.

Title: Method and apparatus for impressing the surface of soap or other material
Inventor: HELY JOHN FREDERICK
IPC: C11D13/28
Filed: 1957-07-22
Abstract: 875,818. Automatic control systems. UNILEVER Ltd. July 2, 1958 [July 22, 1957], No. 23120/57. Class 38 (4). [Also in Group V] Soap or other plastic material is fed along a path which is not straight, from a feed point to the nip of a driven pair of rollers, for impressing the surface thereof, and the roller speed is controlled relatively to the speed of the material at the feed point so that a displacement from said path causes a variation in the roller speed that eliminates the displacement. A soap bar 11 is extruded from a plodder 2 on to a table 3 to pass between guide rollers 4, 4<SP>1</SP> to the nip between impressing rollers 5, 5<SP>1</SP>, and thence between cam-operated wire cutters 8, 8<SP>1</SP>. The axis of the extruder 2 is offset relatively to the aligned nips of the rollers 4, 4<SP>1</SP> and 5, 5<SP>1</SP> so that a variation in the speed of extrusion relatively to the speed of the rollers 5, 5<SP>1</SP> displaces the bar 1 against either of two lugs 9, 9<SP>1</SP> carried by a pivoted bar 10a to rotate the latter in either of two directions. The rotation of the bar 10a actuates a transmitter-repeater means 10b to adjust the speed of a thyratron-controlled variable-speed motor driving the rollers 5, 5<SP>1</SP> to increase or decrease the speed of the latter as the extrusion speed increases or decreases. The drives of the rollers 5, 5<SP>1</SP> and of the cutters 8, 8<SP>1</SP> are coupled directly together. Ink may be applied to the impressing roller 5 by a roller 7.

Title: Process for the production of synthetic resins containing urethane groups
Inventor: MULLER ERWIN
IPC: E01C19/48
Filed: 1964-06-04
Abstract: A cellular or non-cellular cross-linked polyurethane is produced by reacting a compound of M.W. 500-4000 having at least 2 active H atoms and containing a plurality of <FORM:1045806/C3/1> groups where R is alkyl, cycloalkyl, cyanoalkyl or alkenyl.  With an organic polyisocyanate and, if desired, a chain lengthening and/or cross-linking agent.  The starting materials may be prepared by reacting polyfunctional chlorocarbonic esters with N,N1-disubstituted diamines. In a modification the <FORM:1045806/C3/2> group may be bound to a terminal hydroxylalkyl radical, such a starting material being obtained when N-alkyl-o -hydroxyalkylamines or N - cyanoalkyl - o  - hydroxyalkyl - amines are added on to polyether molecules, e.g. polypropylene glycol or tetrahydrofuran after they have been converted into chlorocarbonic acid esters.  In Example (1) the reaction product of N,N1 - dimethylethylenediamine and butane-di-chlorocarbonic acid ester was reacted with naphthylene diisocyanate and foamed with H2O. In Example (4) the reaction product of N-methylethanolamine and the dichlorocarbonic acid ester of polybutylene glycol was reacted with naphthylene diisocyanate and butane diol to produce a rubbery elastic product.

Title: Automatically controlled oil burning heating system
IPC: F23N1/00
Filed: 1922-08-28
Abstract: 196,223. Scott, L. L. Aug. 28, 1922. Electromagnetic switches; springs, arrangement of.-An apparatus for regulating the combustion of fuel in an oil-burning heating-system according to the temperature of the room comprises an electrically driven motor 31, blower 30 and pump 33, Fig. 1, for projecting air and sprayed oil into a zone of ignition, a sparking-plug 8 for igniting the fuel, a high voltage circuit 106, 107 for driving the motor 31, a low voltage circuit derived from the secondary coil 105 of a transformer 104, an electromagnetically operated switch having an armature 50, Fig. 2 for making and breaking the motor and sparking circuits, and a room thermostat 114 for controlling the two electromagnets A, B of the switch. The electromagnetic switch comprises two magnets A, B with a pivoted armature 50 having at its free end a spring-pressed ball 54 and co-operating with two pivoted gravity or spring controlled arms 58, 73 which carry contacts 66, 80, 74 on the upper and lower sides respectively. A fixed bar 93 located between the arms 58, 73 so as to compress the spring 56 controlling the ball as the armature 50 rocks over ensures a mpre rapid action of the arms 58, 73. When the arm 73 is in its lower position the contacts 74, 75 complete the circuit through the motor 31 from the high voltage terminals 106, 107, this circuit including the armature 96 of a safety device 95, while the contacts 80, 81 at the same time complete the circuit through the magnet A from the low voltage coil 105, provided the room thermostat 114 is in engagement with the high temperature contact 118. Both these circuits are broken when the armature is attracted by the magnet A and the arm 73 thereby raised. The primary coil 104 of the transformer is connected through the armature 96 of the safety device in shunt to the motor circuit. When the arm 58 of the switch is in its lower position the circuit through the magnet B from the low voltage coil 105 is completed through the contacts 59, 60, provided the room thermostat 114 is in engagement with the low temperature contact 117; when the arm 58 is raised this circuit is broken and a circuit from the low voltage coil 105 through the contacts 66, 67 to the sparking-plug circuit is completed. Thus, in operation, should the temperature of the room fall from a higher temperature until the thermostat 114 makes contact at 117, the magnet B is energized and draws over the armature 50 which, by lifting the arm 58, breaks the circuit of magnet B and completes the sparking-plug circuit. Simultaneously, the arm 73 drops so as to close the motor circuit and bring the contacts 80, 81 into a " set-ready " position whereby the magnet A will be energized as soon as the room is heated sufficiently to cause the thermostat 114 to make contact at 118. Combustion proceeds until this contact actually occurs, when, the armature 50 being drawn over by the magnet A, the motor and sparking-plug circuits are broken, and the cycle of operations is then repeated.

Abstract: 1,170,366. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 19 May, 1967 [29 June, 1966], No. 23288/67. Heading H3B. [Also in Division H1] In an anisotropic magnetic thin film storage element in which the angular dispersion is sufficient for easily-disturbed stable magnetization to be established along the hard magnetization axis, a film is switched to a desired storage state along the easy axis by applying a first pulse to switch the magnetization from the easy to the hard axis, and, after this pulse terminates, applying a low value second pulse of polarity representing a binary digit to switch the magnetization from the easily-disturbed hard axis stable state to one or the other direction along the easy axis. A matrix store is described, Fig. 7, having word drive lines W1-W3, and orthogonal bit drive lines X1-X3 and sense lines S1-S3, associated with thin film storage elements 10. A first pulse Iw applied to a selected word line switches all the associated cores to the hard direction and induces output pulses in the bit lines which pass to sense amplifiers 16a-16c. Following this pulse, a low value bit pulse I B  is applied to each bit line which switches the associated element to the appropriate storage direction along the easy axis, each bit pulse I B  producing a field having a maximum value less than the creep threshold and a minimum value exceeding Hk sin #, Hk being the anisotropy field along the hard axis and # the dispersion angle. Pulse Iw should produce a field exceeding Hk and preferably exceeding 1.5 Hk. A deposition process is outlined, the parameters being specified for producing the required angular dispersion which should be between 6 and 10 degrees.

Abstract: 642,078. Weighing-apparatus. SIMON (HOLDINGS), Ltd., H. Sept. 8, 1948, No. 23603. [Class 143] The feed gate of an automatic feed weigher is closed gradually from an open position to the dribble feed position, so effecting a smooth throttling of the bulk feed, by the engagement and slow release of its operating lever s by the sector h of a duplex abutment lever pivoting under the control of a dash pot q, the other sector e of said lever being located above a stop b on the weigh beam a'during the bulk feed. At the completion of discharge from the weigh hopper, end u of the beam a rises, pivots lever t about t' and, through engagement of a catch v with the lever t, the arm s is pivoted anti-clockwise about s' so opening the feed gate. Simultaneously a lever m, pivoted at n and controlled by the dash pot q is pivoted clockwise by the beam and through a link k and a crank f pivots lever t about t' and, through enthat its sector h engages under an abutment j on the lever s, maintaining the gate open, and its sector e is located above the abutment b. The abutment j is secured to the lever s by a pivoted catch i so that it may pass the sector h when the lever s pivots anti-clockwise. The weight of material accumulating in the weigh hopper now raises the abutment b into contact with the sector e so locking the beam during the bulk feed and freeing the end of lever m. This lever is then pivoted anticlockwise by its weight p, at a rate controlled by the dash pot q, until its free end again engages the beam and through link k and crank f the abutment lever is also slowly rotated anti-clockwise so that its sector h is disengaged from the abutment j allowing the lever s to gradually pivot clockwise so slowly throttling the bulk feed. At the instant when the abutments j and b are disengaged the gate closes to its dribble feed position and the beam is free to rise, on completion of the dribble feed, so effecting final cut off.
